The natural logarithm of pressure, ln(p), and the reciprocal of temperature, 1/t, are related in the ideal gas law equation. As temperature increases, the natural logarithm of pressure also increases, showing a direct relationship between the two variables.

The vapor pressure of water at 50°C is the same as the vapor pressure at 50°C. Vapor pressure is a function of temperature and does not change for a substance at a specific temperature.
The vapor pressure of water at 10°C is lower than its vapor pressure at 50°C. As temperature increases, the vapor pressure of water also increases because more water molecules have enough energy to escape into the gas phase.
A phase diagram typically includes temperature and pressure as the main factors. It shows how these factors affect the state of matter of a substance, such as solid, liquid, or gas, at different conditions. The diagram can help determine at what combination of temperature and pressure a substance will undergo phase changes, like melting or boiling.
The vapor pressure of supercooled water is higher than that of ice at the same temperature due to the increased mobility of water molecules in the liquid state compared to the solid state. As a result, supercooled water is more likely to evaporate and exert a higher vapor pressure than ice.
The vapor pressure of water at 10 degrees Celsius is lower than at 50 degrees Celsius. As temperature increases, so does the vapor pressure of water because more water molecules have enough energy to escape into the gas phase.
